PRESERVATION AND PREPARATION FOR TRANSPORTATION OF CTTONSEED.

Application led May 20,

To all whom- ?z? maq/ conca/wi.'

Be it known that I, ALFRED lViLLmM MAC- lumiere, a subject oi' the kingof England,

residing at North Ferriby, East Riding of relating to the preservationand preparation 'for transportation of cotton'seed.

In the specification of my evo-pending United States application No.562,561, May 20,1922,thereis described a method of preparation fortransport and (or) preservation of oil-yielding raw material, such asnuts, seeds v and copra, said method Consisting in compressingquantities of the material, in bulk, under a pressure insuiiicient toexpress any of the contained oil,'or any appreciable quantity of thecontained oil, but sufiicient to form y blocks or packages of increaseddensity.

The present invention deals with the application of the above process tothe treatment of cotton seeds. Thus, according to the present inventionthe seeds are prepared for transport and (or) preserved from de-lcomposition by compressing quantities thereof in bulk, under a pressureinsufficient to express any appreciable quantity of the contained oil,but sufficient to form a package ot greatly reduced bulk. It is animportant feature of the present invention that the pressures `employed'for compacting the masses of seeds shall not be suilicient to bringabout any substantial expression of oil into the spaces between the'particles` In the preferred method of carrying the invention intoeifect the compression pressure is such that none of the contained oilis expressed, while the material'is Jformed into a coherent block.Conveniently the compression pressure employed is in the region of twotons per square inch on the block, but it will be understood that theactual compression pressure depends to some extent on the quality of theseeds to be treated, and no single value of pressure can be given asapplicable in general to cot-ton seed. Provided, however, the pressureis within the limits hereindescribed, the objects of the invention willbe achieved.

The compression restricts access of the atmosphere to the seeds and thecontained oil, and preserves the oil accordingly. By

192,2. Serial No. 562,562'l compressing' the cotton seed accompanied vbycorresponding exclusion of air, the risk of Spontaneous combustion andlire is consider'- ably lessened.

rlhe invention includes a block or package of cotton seed, prepared inthe manner above set forth.

One preferred method of carrying this invention into effect will now bedescribed in detail by way of example only, reference being made to theaccompanying drawings in which- Figure 1 shows in elevation one suitableform of press; and

Figure 2 is a part sectional plan on the line 5-5 of Figure 1.-

Like reference numerals indicate like parts throughout the two figuresof the drawings.

vThe press comprises two upright columns 10 of I-section connected topand bottom by cross members 11./ The press is adapted to apply pressureat top and bottom simultaneously and for this purpose two hydraulic yplungers 12, 13 are provided, the former being movable downwardsagainst' the action of counter-balanceweights 14- which lhave a.steadying action on the pressure and'als'o serve to ret-urn the upperplunger to its normal inoperative position when the hylThe weightsdraulic pressure is released.

14 extend in width beyond the sides of Ythe columns 10, the outerflanges of the columns being engaged in -recesses in the weights wherebythe latter areguided in their vertical movement. The control gear forthe plungers is indicated generally by the reference numeral 15. r,Thehea-d plate of each press plunger is provided with slats 16 runningparallel to the webs of the columns 10. .The compressionl chambercomprises an upright hollowl box of rectangular cross-V section, open attop and bottom, and with its sides (17, 16, 19, 20) strengthened byangle and channel stiffeners 21. "The box is secured between the columns10 oiE the press,

the angle stii'eners at the lower ends oi' the sides 18 and 2() beingpivotally ysecured-to channel plates 22, which lare themselves bolted tothe flanges of the 'colifimns` The sides 17 and 19 constituting thefront and back of the box, are hinged to the side 20 and may be swungrelatively thereto about the hinges 23 at themeeting edges ofl therkthree sides. The side 20 is resiliently secured to the adjacent column10 by bolts 24 which pass through apertures in the web of lthe VjawsintoV the position shown.. In order. thatgthe-box may be properlyaligned before column, have their outer ends engaged by nuts 25, and areencircled by springs 26 in compression between the box side and the webof the column. rIhe side 1S isv connected by means of two shortlinks 27to the adjacent .column.10. The box isI held .together at the meetingedges of the sides 17 and 19 with the side 18 bytwo setsofsecur-l ingdevices. One set comprises spring fasteners 28-in the regionof the topand bottom ofthe box, and` the other set coni. prises varms 29 Vwithbifurcated jaws 30 adapted to engage with co-operating lugs 31.0n-1thebox side 187 andv to be held in Vthe engaged position (shown clearly inFigure 2) by means o1 swivel bolts 32 and winged nutsi.:V The bolts32are-pivoted .to the side 18 and-may be swungthrouglrthe forked'pressure is applied there is provided a spind-lell inscrew-threaded*.engagement in the web of the column 10-adjacent-the box.
